Both the upper end of the air-pipe 10 by an ordinary IOO oil and air are supplied under pressure, as is coupling band or collar, and the upper end of well understood in connection with this class the oil-pipe 9 screws into a socket in the un-' of lamps, and usually the pressure upon the der side of the head. The upper end of the 50 oil in the reservoir is obtained by the comoil-valve rod, which is screw-threaded, works pressed air, which serves to spray the oil at in a correspondingly-threaded socket in the the burner. head 1 and is formed with longitudinal chan- The air-pipe leads to a casting 12, forming nels 8, which permit the passage of the oil to the base of the lamp and bolted to the post or the valve and burner. The conical valve 7 on the end of the rod is seated in an aperture pression in the upper face of the head 1, which is covered by a horizontal partition 5, bolted to a horizontal flange surrounding the edge of the head 1. In the partition 5' are arranged nozzles 5, each of which is concentric with one of the nozzles 6 and arranged in suitable proximity thereto. The oil issuing from the nozzle 6 mingles with the volume of compressed air in the chamber 5 and both are discharged through the nozzles or burners 5. These nozzles being inclined slightly toward each other, the flames therefrom commingle, the heat of each assisting the other in producing a broad intense flame.

The diaphragm 5 is provided with a vertical annular flange 5 and a horizontally-projecting upwardly-curved annular flange. 5 A correspondingly-shaped cover 5 rests upon the edge of this flange and carries centrally the combustion-chamber 4:, which is of the ordinary shape. The lower end of the combustion-chamber projects below the upper end of the vertical flange 5 as shown. The flange 5 is formed with a series of apertures in connection with which a correspondingly-apertured annular sliding plate works, the plate being moved by a handle 5 to regulate the amount of air admitted. The air entering through these apertures passes up over the vertical flange 5 then down and up into the combustion-chamber. Air may or may not be thus admitted, as may be found desirable.

Referring now to the manner of adjusting the air and oil supplies and the method of turning the air and oil on and off, the oilvalve rod 8 and the air-valve rod 13 are each provided with a wheel-handle 23 16. The periphery of each wheel is cut out or formed with a recess curved to correspond with the periphery of the adjoining wheel. The wheel 16 may be loosened on the air-valve rod, set to the desired point, and clamped by the nut 17. In like manner the wheelof the oil-valve rod may be similarly adjusted by means of the nut 24. The wheel 16 is provided with a projecting stud 16 and the wheel 23 with a similar stud 23. When the lamp is not in operation, the wheels occupy the position illustrated in Fig. 5. The periphery of the wheel 16 occupies the recess in the wheel 23,.

and consequently the oil-valve cannot be moved. The wheel 16 may, however, be moved in the direction of the arrow to open the air-valve, and this movement maybe continued until the stop 16' thereon strikes the stop 23' on the wheel 23, when the depressions in the peripheries of the wheels are opposite each other. The wheel 23 may then be rotated in the direction of the arrow to open the oil-valve, and its extent of motion in this direction may be regulated bya radially-proj ecting stop-arm 25, adjustably clamped upon the valve-rod, as shown. By the adjustment of the stop 25 and the adjustment of the wheels upon the valve-rods the amount of air and oil supplied to the lamp may be regulated.

Obviously in starting the lamp the airvalve must first be'operated,and it is equally plain that in extinguishing the lamp the oilvalve must first be closed.

So far as I am. aware I am the first to provide a mechanism in which the air-valve handle must be moved to the proper position before the oil-valve handle can be independently moved to turn on the oil, and vice versa, and this idea may be embodied in other mechanical forms. I do not, therefore, limit myself to the particular organization shown.

In Figs. 6 and '7 I have shown a slightlymodified construction, in which six burners instead of two are shown. The central one throws the flame vertically, while the surrounding burners are inclined toward the cent-er. The operation is like that already described, and no additional description is necessary.

I claim as my invention 1. In a spray-lamp, the combination, substantially as set forth, of two or more spray burners or nozzles inclined toward each other, means for supplying oil and air thereto under pressure, a narrow combustion-chamber, open at the top and into which the burners or nozzles discharge at the bottom, arranged above the burners and constituting a chamber or passage-way above the burners, through which the mingled oil and air and flame rise.

2. In a spray-lamp, the combination, substantially as set forth, of a series of spray nozzles or burners, one being central and the others arranged around and inclined toward it, a combustion-chamber into which all the nozzles discharge,open at the top and arranged above the nozzles and constitutinga chamber or passage-way above the nozzles, through which the mingled oil and flame rise.

The combination, substantially as set forth, of a narrow combustion-chamber open at the top, through which the flame passes and which prevents the flame from spreading laterally, aseries of oil-nozzles 6, through each of which the oil is forced under pressure, an oil-supply pipe communicating with all the oil-nozzles, a valve regulating the supply of oil to the oil-nozzles, a closed chamber 5, into which the oil-nozzles project, a compressedair-supply pipe or passage leading into said closed chamber, a valve regulating the supply of air through. said passage, and the nozzles 5, arranged above the oil-nozzles and leading from the closed air-chamber and through which the mingled oil and air are discharged under pressure into the combustion-chamber.
